The number is n =
32
Answer:
The number is 4
Step-by-step explanation:
Let the number be n
Twice the number : 2*n = 2n
Half the number : 1/2 n
\(2n+ \frac{n}{2}=10\\\\\frac{2n*2}{2}+\frac{n}{2}=10\\\\\frac{4n}{2}+\frac{n}{2}=10\\\\\frac{5n}{2}=10\\\\5n=10*2\\\\5n=20\\\\n=\frac{20}{5}\\\\\)

The lines shown below are perpendicular. Find the slope-intercept form of the equation of line y2.
y2
(-3,7)
Y₁ = 3x-6
Answer:
\(y2 = -\dfrac{1}{3}x + 6\)
Step-by-step explanation:
Perpendicular lines have slopes that when multiplied will result in a value of -1
In other words, the slope of y2 = - 1/(slope of y1)
y1 = 3x - 6
Slope of y1 = 3
So slope of y2 = -1/3
Equation of y2 is of the form
\(y_2 = -\dfrac{1}{3}x_2 + b\)
The line passes through (-3, 7)
To find b plug in y2 = 7, x2 = -3 into the above equation and solve for b
\(7 = -\dfrac{1}{3}(-3) + b\)
=> 7 = 1 + b
b = 7-1 = 6
So the equation of line y2 is
\(y2 = -\dfrac{1}{3}x + 6\)
Hint: If you look at the graph, line y2 crosses at b = 6
We need not have used equations to solve for b but we have to be careful. We can at least the graph value to see if our b value is close to it

The given function k is a composition of two functions m and n so that k(x) = (m ∘ n)(x). k (x) = startfraction 2 over rootindex 4 startroot 4 x minus 7 endroot endfraction if n(x) = 4x â€" 7, m(x) must be equal to which expression? 2 startroot x endroot x rootindex 4 startroot x endroot startfraction 2 over startroot x endroot startfraction 2 over rootindex 4 startroot x endroot endfraction
The expression for m(x) in the composition k(x) = (m ∘ n)(x), where k(x) is given as 2/(√(4x - 7)), and n(x) is given as 4x - 7, is m(x) = √x.
To determine the expression for m(x) in the composition k(x) = (m ∘ n)(x), we need to substitute the given functions n(x) and k(x) and solve for m(x).
Given:
k(x) = (m ∘ n)(x) = 2/(√(4x - 7))/√(4x - 7)
n(x) = 4x - 7
Substituting n(x) into the composition, we have:
k(x) = 2/(√(4(4x - 7) - 7))/√(4(4x - 7) - 7)
= 2/(√(16x - 28 - 7))/√(16x - 28 - 7)
= 2/(√(16x - 35))/√(16x - 35)
From the given expression for k(x), we can see that the denominator of the fraction contains the term (√(16x - 35)). Therefore, m(x) should contain the reciprocal of this term to cancel it out when combined with n(x) in the composition.
Hence, m(x) must be equal to:
m(x) = 1/√(16x - 35)
Among the given options, the correct expression for m(x) is:
2/(√x) * √x/√(4) = 2/(√x) * √x/2 = √x

The density of the given metal is 19.3g/cm³ . Then, the correct answer to this given question is Option E.
The given mass of the metal is 611 g and it is kept in a elevated cylinder that contains 25.1 mL of water,
Now, let us increase the water level to 56.7 mL. The metal volume can be evaluated by subtracting the initial volume from the final volume of water released by the metal.
Hence,
Metal volume = final volume - initial volume
= 56.7 mL - 25.1 mL
= 31.6 mL
Therefore,
Density = Mass / Volume
= 611 g/31.6 mL
= 19.3 g/cm³

what is the difference between experimental and quasi experimental research
The experimental research provides higher control and allows for stronger causal inferences, while quasi-experimental research is more suitable when random assignment is not feasible.
Experimental and quasi-experimental research are two approaches used in scientific studies, but they differ in terms of their design and the level of control over variables.
⇒ Experimental research involves the manipulation of an independent variable to observe its effects on a dependent variable, while controlling for potential confounding variables. It assigns random assignment of participants to different conditions, allowing for causal inferences.
The researcher has control over the variables and can establish cause-and-effect relationships.
⇒ On the other hand, quasi-experimental research lacks random assignment of participants. Instead, pre-existing groups or naturally occurring variations are used. The researcher still manipulates the independent variable but cannot randomly assign participants. This limits the ability to establish strong causal relationships.
⇒ Quasi-experimental designs are used when random assignment is not possible. They are useful for studying phenomena in real-world settings, but caution must be exercised in drawing definitive causal conclusions.

The main difference between experimental and quasi-experimental research is that experimental research involves random assignment and control groups, while quasi-experimental research lacks random assignment and control groups.
Experimental and quasi-experimental research are two common research designs used in social sciences and other fields. They differ in terms of random assignment, control groups, and the establishment of causality.
Experimental Research:
Experimental research involves the manipulation of an independent variable to observe its effect on a dependent variable.It typically includes a control group and an experimental group.Participants are randomly assigned to each group, ensuring that the groups are comparable at the start of the study.This random assignment helps minimize the influence of confounding variables and allows researchers to establish cause-and-effect relationships.Experimental research is often conducted in laboratory settings, where researchers have more control over variables.quasi-experimental research:
Quasi-experimental research also involves the manipulation of an independent variable, but it lacks random assignment and control groups.Participants are not randomly assigned to groups, which can introduce potential biases and confounding factors.Quasi-experimental designs are often used when random assignment is not feasible or ethical.They can provide valuable insights and help researchers study real-world phenomena.However, they do not establish causality as strongly as experimental designs.Overall, experimental research provides stronger evidence for cause-and-effect relationships, while quasi-experimental research is used when random assignment is not possible or practical.

Which of the following is the best interpretation of 0 6 H(t) dt?
(A) The temperature of the room, in degrees Celsius, at 6:00 A.M.
(B) The average temperature of the room, in degrees Celsius, between midnight and 6:00 A.M.
(C) The change in the temperature of the room, in degrees Celsius, between midnight and 6
(D) The rate at which the temperature in the room is changing, in degrees Celsius per hour, at 6:00 A.M.
It will represent the change in temperature between midnight and 6, the correct option is C.
Which is the best interpretation of ∫H(t)*dt?
H(t) is the rate at which the temperature changes. So, if we integrate H(t), we will get the change of temperature.
In this case, we have:
\(\int\limits^6_0 {H(t)} \, dt\)
This will give the change in temperature between 6:00 AM (represented by the 6) and midnight (represented with the 0).

If 4 rectangles were put together to form a shape with a perimeter of 88.then what is the breadth of each recangle
The breadth of each rectangle is 11 units.
Let's consider that each rectangle has a length of l and breadth of b. We have been given that the perimeter of the shape that is formed by putting together the 4 rectangles is 88 units. We know that, the perimeter of a rectangle is given by the formula 2(l + b).
Therefore, the perimeter of the shape is given by the formula: P = 2(l + b) + 2(l + b) = 4(l + b)
From the given information, we know that the perimeter of the shape is 88.
Therefore,4(l + b) = 88
Dividing both sides of the equation by 4, we get: l + b = 22
We have found the relationship between the length and breadth of each rectangle.
Now, we need to find the value of the breadth of each rectangle.
We know that there are 4 rectangles placed side by side to form the shape.
Therefore, the total breadth of all 4 rectangles put together is equal to the breadth of the shape.
Hence, we can find the breadth of each rectangle by dividing the total breadth by the number of rectangles.
Let's denote the breadth of each rectangle as b'.
Therefore, b' = Total breadth / Number of rectangles
b' = (l + b + l + b) / 4b' = (2l + 2b) / 4b' = (l + b) / 2
We have found that the sum of the length and breadth of each rectangle is equal to 22 units.
Therefore, the breadth of each rectangle is half the sum of the length and breadth of each rectangle.
Substituting this value in the above equation, we get:b' = (l + b) / 2b' = 22 / 2b' = 11
Therefore, the breadth of each rectangle is 11 units.
